STAMPING-MACHINE.

Specification of Letters Patent.

Patentedlll ec. 12, 191 6.

Application filed February 1'7, 1914. Serial N 0. 819,177.

To all whom it may concern:

Be it known that I, J oI-IN E. HIRES, a citizen of the United States, residing at Malvern, county of Chester, State of Pennsylvania, have invented certain Improvements in Stamping-Machines, of which the following is a specification.

One object of my invention is to construct a machine for marking cans as they are moved past a given point; the number, or other indicating mark, being impressed thereon without stopping the continuous movement of the belt or carrier.

A further object of the invention is to provide means for stopping a can in its travel and centering it under the stamping mechanism. 7

A still furtlier object of the invention is to provide means for inking the type by means of the blow of a hammer and to stamp the cans by a hammer-action of the type carrier.

This invention has for its purpose the impression of a special mark on each can for identification, although it can be used for placing numerals, or other marks, on cans and containers without departing from the essential features of'the invention.

In the accompanying drawings: Figure 1 is a front View of my improved stamping machine; Fig. 2 is an end view, looking in the direction of the arrow 2, Fig. 1; Fig. 3 is a rear view; Fig. 41 is a view, in diagram, showing the impression head raised in line with the ink pad, and Fig. 5 is a section on the line aa, Fig. 3.

Referring to the drawings, 3, 3 are two angle rails which support the belt 2-which conveys the cans w from the filling or other machine. These angle rails are suitably supported at intervals. The frame 1 is secured to the rails at any convenient point so that the stamping mechanism will overhang the cans.

4 is a frame which supports thestamping mechanism and this frame is adapted to guideways 5 in the base 1 and can be vertically adjusted by a screw 6 having a handle 7 This frame is adjusted not only to accommodate cans of different sizes, but also to regulate the force of the blow of the type carrier.

It will' be understood that special ink is used in this instance which, when applied to a can, dries quickly and which is not'readily removable after once being applied. To properly apply this ink, it requires a blow of the impression head and it also requires a blow to supply the type carrier with ink. Therefore, I construct the mechanism so that the impression is made by a blow, the ink being supplied to the type in the same manner.

In order to center a can in proper alinement with. the impression head, I provide three slidingfingers 11, 12 and 13, which have their bearings in the frame 41 and project into the path of the cans m as they are moved forward on the belt 2. These fingers are moved into and out of the path of the cans by arms 14, which are carried by a rock shaft 15. The arm controlling the finger 11 is yieldingly connected to the rock shaft 15 through the medium of a spring 16, while the arms controlling the fingers 12 and 13 are rigidly secured to the shaft.

As the cans are fed past the stamping. mechanism, the fingers are projected into the path of the cans and a can is brought up against the central finger 12. 'When this finger is withdrawn, the can is carried forward by the belt and when the fingers are again projected it is stopped in alinement with the stamping head by the finger 13. The finger 11 will usually stop the can first, so that when the can is moved forward it will be in the proper position and will strike the finger 12, but should the finger 11 be projected against the can instead of into the space between the cans, it will yield and the can will be fed forward until stopped by the finger 12. Thus, each can is momentarily stopped in the proper position under the stamping head without interfering with the continuous movement of the belt.

On the base 1 are brackets 8 to which is secured a longitudinal guide rail 9 located close to the path of the cans and on the frame is a rail 10 so that each can passes between these two rails.

The rock shaft 15 has an actuating arm 16 which is engaged by the arm 17 on the vertical shaft 18 having its hearings on the frame of the machine and is returned to its normal position by a spring 19. One end of the spring is attached to a collar on the shaft 15 and the other end is attached to a pin on the frame 4. The vertical shaft 18 has an arm 20 provided with a pin which engages a cam 21 on the shaft 22 to which power is applied. A spring23, secured in the present instance to the lower end of the shaft 18,

tends to hold the pinon the arm 20 against the cam'2l so that as the'main shaft revolves the vertical shaft reciprocates, causing a like movement to be imparted to the shaft 15 and its fingers. On the shaft 22 is a belt Wheel 23 by which the mechanism is driven.

Pivoted at 24, on the opposite side of the frame to the mechanism hereinbefore described, is an arm '25 having a long bearing 26 through which extends the stem 27 carrying at its lowerenda head 28in which is mounted the type form 29. A pin 30 on the stem 27 extends through a slot 31 in the bearing 26 so as to prevent the head from turning in the bearings. Between a collar 32 on the stem 27 and the bearing is a spring 33, tending to lift the head 28 and to hold it in the position illustrated in Fig. 1. Pivoted at 34 to the frame 4 is an arm 35 carrying an inking pad 36, and connecting the arm 35 with the arm 25 is a link 37 so that, when the arm 25 is raised, it causes the inking pad to come in alinement with the stamping head, as illustrated in Fig. 4c.

Projecting from'the hub on the arm 25 is an arm 38 actuated by a cam 39 on the main shaft 22 so that the stamping head is lifted and then dropped in order to allow the type to strike the end of a can and make an impression. When the stamping head is in its raised position the type is inked by a hammer striking the end of the spindle 22 and causingthe spring 23 to be compressed so that the type will come in contact with the inking pad 26. The hammer L0 is mounted on an arm 41 carried by a shaft 42 having an arm 43 actuated by a cam let on the shaft A spring 45, at the back of the frame 4, is connected to the shaft 42 and to the frame at 46. The hammer 4:0 is raised by the cam 44 and, as soon as the cam leaves the hammer, it is forced down by the spring 45 coming in contact with the end of the stem 27, which forces the type against the inking pad.

7 The mechanism is so timed that as the cans are located under the stamping head, the stamping head makes an impression on the end of a can and as it is raised the can is fed forward and another can is positioned and the type of the inking head is inked by the mechanism described above. Another impression is made and so on as can after can is fed forward. The stamping operation is accomplished without stopping the car men The mechanism can be adjusted to cans of different heights by actuating the adjusting screw 6 atthe bottom. The fingers are spaced a sufiicient distance apart to accommodate the varying diameters of cans of different sizes.

While I have described my invention as particularly adapted for marking cans, it

will be understood that it can be used for marking other containers, provided they are of a sufficient size and of a shape to be traversed past the mechanism and to be stamped by the impression head.

I claim:
